We had been looking forward to our vacation for months. After the cold of the winter, a couple of weeks in the sun was all we could think about. It had the promises of the beach, the ocean, long walks in the moonlight followed by sex (on the beach if possible), pina coladas, and margaritas. The sight of gorgeous men and women who were there for the same reasons… Sun… Sex… More Sun… And of course… More SEX.

What we didn’t know was that these couple of weeks would shape the rest of our lives, would change the way we looked at sex, our fantasies, our needs, our tendencies…

My wife, as a typically shy woman, had always fantasized about having sex in public places. She had also expressed an interest in having sex in front me… With another man. “I would love to cuckold you” she once told me with a twinkle in her eyes and I remember feeling both alarmed and incredible turned on when I first her heard her say that to me.

We had just spent the whole day lazying around at the beach and were taking a rest in our cabin and were actually trying to find ways to convince each other to call it a day and have an early night. We were pooped. Ready to call it a day and sleep.

As destiny would have it however, we decided to take a quick last stroll under the moon light and head on home for a much needed rest.

The evening was gorgeous, the moon in full bloom and as we started to walk by the ocean, our reservoir of energy was soon replenished and we found ourselves walking further than we had planned.

When we realized how long we had walked, we stopped to turn around and walk back and seeing how beautiful my wife looked on the beach that night, I grabbed her and held her in my arms. We fondled and we were both practically naked in each others’ arms when we heard steps coming towards us. It was too late to do anything so we just stood there, half naked, with my wife’s gorgeous butt in plain view and my dick in her hand.

We thought who ever it was who was walking towards us would see the intimate nature we were in and respectfully walked away and we were waiting for the steps to fade away, but they kept on coming towards us, louder and louder until they stopped, right behind my wife.

I really didn’t expect it but my hard cock twitched in my wife’s hand and I heard an ever so light sigh coming from her as she was making no attempt to release me. On the contrary… Her hand which had stood largely still started to move up an down my cock. It was a really slow movement. There we were, my wife who was nearly completely naked, with my dick in one of her hands, and her naked butt in full view of a stranger who was standing right behind her and who had not said a word. I was as hard as I had even remembered… It was an incredible sensation.
